Is there any way to identify what the rated output for a stock Mopar alternator. I want to upgrade my early (1965) alternator to a 1978 alternator that I pulled from a pickup. I realize that I will have to ground one of the field terminals. Don't want to go through the aggravation of the swap if the outputs are the same.



I was considering this but I was told that that these later alts like you are talking about might be rated for more amps, but suffer the same big problem that the older ones do: low charge at idle. I don't know if that's 100% true, but my old one wouldn't keep up with electric fuel pump and the denso handles all of the electrics with ease.
